00:11Domestic cats are a paradox.
00:15They have lived with people since the beginning of civilization.
00:23But they became domesticated without losing their feline nature.
00:27Your independence.
00:31And their ability to live without us.
00:36However, it's obvious that they like people.
00:39And a lot of people like them.
00:40Cats and people live as partners.
01:07The complete guide.
01:12Domestic cats.
01:18And it's a partnership that can begin in youth.
01:28Cats, however, live shorter lives than people.
01:30And they can't afford a long childhood.
01:37A six-week-old baby, the same age as these kittens, cannot run, jump, and explore.
01:47And at five months old, even though they are still much younger than that baby, the kittens will already be...
01:53adults.
01:54But for now...
01:58Life is full of adventures.
02:06At just six weeks old, they are already developing the wide range of feline skills.
02:14It just needs some refinement.
02:22Even the simplest toys can be educational.
02:26Teaching, for example, how to hunt.
02:35And what is most important to a cat?
02:38Strengthening ties with people.
02:41If they don't do it now, they'll never do it.
02:44And they will grow wild.
02:48Living with people was good for the cats.
02:51With the increase in the human population, the number of cats also increased.
02:55Today, there are approximately 450 million cats on the planet.
02:58What makes the domestic cat the most successful feline species?
03:03And that didn't make them lose their independence.
03:07Cats live both in the center of the human world and on its fringes.
03:14A domestic cat still retains all the physical qualities inherited from its wild ancestors.
03:20Elasticity and agility.
03:30The ability to avoid injury when falling, using the righting reflex.
03:36It is the valuable ability to spin in the air and land safely on its padded feet.
03:48Domestic cats, like wild cats, never do more than is necessary.
03:53And they spend up to 18 hours a day sleeping.
03:58In nature, cats tend to hunt at night.
04:02And domestic cats have retained the eyes of a hunter.
04:05Eyes that can see in light six times dimmer than humans can.
04:10Centuries of domestication have not drastically changed the size of cats.
04:15In this respect, almost all of them are similar.
04:18But among the races, there are many other distinctions.
04:22often provoked to satisfy certain tastes.
04:25Sometimes inexplicable, the actions of human beings.
04:32But cats, unlike almost all other domestic animals,
04:36They have virtually the same appearance and behavior as those in the wild.
04:42Your relationship with people is a partnership.
04:57A partnership that dates back almost 4,000 years,
05:01to one of the first civilizations on the planet,
05:05Ancient Egypt.
05:12In the homes and streets of Egypt,
05:14Today there is a certain type of cat that is slender and vigorous.
05:18which is very similar to the first cats that became associated with humans.
05:25These could be cats that the ancient Egyptians raised and even adored.
05:31And here is its origin, the Libyan cat.
05:34A wild cat from North Africa.
05:38A cat that adapted to change.
05:42Egyptian civilization grew with the invention of agriculture.
05:46People started storing grain, which attracted rodents.
05:49And the rodents attracted the wild cats.
05:52Wild cats were welcomed as hunters and scavengers.
05:56Thus, a coexistence solution was formed between the cats and the farmers.
06:02Over time, cats ended up living with people inside their homes.
06:07Domestication was an agreement made between equals.
06:10And we never control cats.
06:13However, it seems that even today we don't quite understand this.
06:17Karen Overall is an expert in animal behavior at the University of Pennsylvania.
06:21We don't understand cats, which is interesting.
06:24Because they have lived alongside human civilizations for thousands of years.
06:27And part of the problem is that we haven't domesticated, so to speak,
06:31Or we develop the cat as a domestic animal, as we did with the dog.
06:36We let them stay with us because they were excellent hunters.
06:40They eliminated the rodents and therefore controlled the diseases.
06:44The Black Death was extremely limited to certain areas.
06:47Because the cats killed the rats that carried the fleas that transmitted the disease.
06:52And we wanted the cats to stay with us, maintaining this kind of no-touch relationship.
06:58But we never really worked with and domesticated cats for specific behaviors.
07:04You don't see a cat herding cattle like a Border Collie.
07:08You won't see a blind man's cat.
07:10They are fantastic companions.
07:12But I don't think anyone would really want to depend on a cat for that sort of thing.
07:17They are extraordinarily intelligent and retain all their feline qualities.
07:22They are completely individualistic, and we don't give them the credit they deserve for it.
07:32There are currently 37 varieties of felines.
07:35And the first thing people recognize in any of them is their characteristic feline appearance.
07:42It's the way you move.
07:45The tendency to live and hunt alone.
07:49The fact that, unlike other carnivores such as dogs and bears,
07:53They feed exclusively on meat.
07:59And people recognize this feline trait because cats live alongside them.
08:06And they are often just as familiar as other people.
08:15So what makes a cat the animal that it is?
08:22What gives it its grace and sinuousness?
08:29His excellence as a hunter?
08:34It starts with the basic structure.
08:36The skeleton is lightweight and flexible, yet strong.
08:44The spine includes the tail, which provides balance.
08:47And that's the central point of the cat's incredible elasticity.
08:55The discs between the vertebrae are thicker than in most other animals.
09:00And the connections between the bones are looser, increasing mobility.
09:10Like a dancer on pointe, the cat walks on its toes.
09:15As a result, the leg length and stride size increase, and the cat gains speed.
09:25And that's also why, surprisingly, that joint is both the cat's ankle and the beginning of its paw.
09:32The bones of the leg are very long.
09:37Only the toes make contact with the ground, increasing momentum and jumping ability.
09:47Part of the secret to cats' agility lies in the design of their shoulders.
09:53The clavicle is free and the shoulder blades are not attached to the main skeleton.
10:00Everything is held together by ligaments and muscles, allowing the shoulder blade to move freely.
10:07And the muscles function somewhat like springs.
10:10They are much more flexible than the muscles of most mammals.
10:14They expand and contract like elastic bands, giving the cat the strength to jump several times its own height.
10:21A human being with muscles like a cat's would leap from the ground to the top of a house.
10:27When a cat jumps, the force comes from the muscles in its hind legs.
10:32Each muscle is made up of many muscle fibers.
10:37They consume a lot of energy to contract quickly.
10:40And when they loosen up, they're like catapults.
10:44Good for bursts of speed, but too tiring for long journeys.
10:49The cat is a sprinter, not a marathon runner.
10:53The cat is also a natural acrobat.
10:56This is because its chest is very narrow and its front legs are very close together.
11:03Whether he's on a tree branch or atop a fence, he walks as if he were on the ground.
11:13Since they started living in houses, cats haven't always been able to exercise their talents.
11:20But there are ways to transform the interior of a house into a surreal replica of the world outside.
11:31This is the world that belongs to Molly, Little Jimmy, Bernard, Tom, Frank, and four other cats.
11:41Like most people, you start with two cats.
11:43And at that time, we thought the two of them were a perfect family.
11:47But one thing literally led to another and now we have nine.
11:51And nine cats seems normal to us.
11:56We noticed early on that when we left for work every day, the cats stayed at home.
12:01And we realized that, hey, if they could own 90% of the property, the house was actually theirs.
12:07So we decided to make things easier for the users, in this case, the cats.
12:13One thing we know about cats is that they like to climb and walk on things.
12:18Cats really like heights.
12:21They love to look down on us.
12:23And now we have about 40 meters of walkway reaching almost every room.
12:28And where we are, they are.
12:33How was your day today, Tom?
12:36Hi, Frank.
12:37Frank visits Bob's wife, Frances, while Tom receives all his attention.
12:44But only for a short time.
12:54In this age-old partnership between people and cats, people derive pleasure from their part of the agreement.
13:00And cats enjoy an indoor environment that is just as interesting and stimulating as the outdoor one.
13:06But safer.
13:09We created a catwalk that would be not only suitable and fun for the cats, but fun for us too.
13:21Another requirement for partnering with cats was that these essentially solitary animals learn to live with one another.
13:28the others.
13:31At the Institute of Anthrozoology in England, John Bradshaw has been studying how cats interact with humans and
13:38with other cats.
13:39His laboratory is home to 11 cats who live in a close-knit group.
13:47Cats are often described as selfish, in contrast to dogs, which are much more loyal animals.
13:52But I don't believe cats have a concept of loyalty.
13:56They view their interaction with people as a partnership between equals, rather than a relationship of subservience.
14:01Of course, they are also sociable.
14:04I think we underestimate cats in this respect.
14:06They are very sociable with people and can become sociable with other cats when raised in the right environment.
14:13A famous study on free-range farm cats conducted in 1977 by Oxford biologist David MacDonald showed how many
14:22Cats can be sociable.
14:24Professor MacDonald's team placed radio transmitters on four cats and monitored them for a year.
14:32Almost all of the cats' movements were recorded.
14:38There were three females and one male.
14:40MacDonald observed that the females remained near the farm, in a close and friendly group.
14:47The male spent two-thirds of his time away, wandering, partying, and hunting rats.
14:53But he always came back home.
14:58The highlight of the study was when the team witnessed one female helping another to give birth.
15:07She acted as a midwife, including when it came to cutting the umbilical cord.
15:12Later, the two shared a shelter and cared for each other's offspring.
15:17This was the first scientific record of such close cooperation between semi-wild domestic cats.
15:23And it proved that, left to their own devices, they can be very sociable animals.
15:27What MacDonald's work showed was that cat society does not follow a linear hierarchy.
15:33like that of a dog or a wolf.
15:35It's much more of a partnership between equals, a cooperation between related females.
15:39that gather around a specific place where there is plenty of food and space for the young.
15:46Modern pest control techniques are driving working cats, rat catchers, into unemployment.
15:53But there are still many places in the world where semi-wild cats live together.
15:58On the Italian island of Stromboli, these cats are everywhere.
16:03Here, cats are rarely kept as pets.
16:06But there are kind people who take care of them and feed them.
16:12One of them is Mrs. Uschi, from the village of Ginostra.
16:16For over 40 years, she has been feeding a colony that is constantly changing.
16:23Cat groups exist where people provide large quantities of food.
16:28And they can do this by feeding them deliberately or accidentally.
16:32For example, leaving food outside restaurants.
16:35When cats realize that this is a regular source of food,
16:38They gather around it and begin to form a colony.
16:41And these colonies are wonderful opportunities to study cat behavior.
16:45Because everything happens in a restricted area that we can observe.
16:49Otherwise, they spread out too much and it becomes much more difficult.
16:51For cats, social interaction involves things that their wild ancestors didn't worry about.
16:58For example, constant communication.
17:01A wild cat can use scent to mark its territory.
17:05But these cats have transformed scent marking into a language.
17:09With urine and special glands on the face,
17:12They leave messages as distinctive as a voice or a signature.
17:21Cats have a highly developed sense of smell.
17:28The mucous membrane of a cat's nose, where scents are imprinted,
17:32It has twice the area of its human counterpart.
17:35And just below that is a second odor detector, the Jacobson's organ.
17:40The cat breathes air through its mouth, and its special cells analyze the particles.
17:49And smell is not their only means of communication.
17:52Cats rub against each other too.
17:54We believe this is a very important sign in cat society and in the cat-human relationship.
17:59Cats tend to rub against other cats that are slightly larger or more aggressive.
18:04Females tend to rub against whichever male they want.
18:09When they rub against us, they are acknowledging that we are stronger.
18:14Not superior, but slightly larger.
18:17They show some kind of deference to acknowledge that we are bigger,
18:21But they still want to be friendly.
18:26And then there's the purring.
18:29Purring seems to be an invitation to some kind of attraction and also to physical contact.
18:33Cats purr when they are happy and want the company of another cat or their owner.
18:39or when they are in a lot of pain.
18:41For example, a cat that has been run over.
18:43It seems bizarre because people associate purring with pleasure.
18:47But it's not about pleasure, it's about wanting attention.
18:50They are trying to get help in that particular situation.
18:53Cats purr by vibrating their outer vocal cords, and it seems that each cat has a specific frequency.
18:59One of the things we discovered by observing cats on farms and elsewhere
19:04It's because they are very quiet.
19:06Unless there's a fight or something going on,
19:09Cats don't make much noise.
19:11One of the things they do least is meow.
19:16And we think this happens because the cat learns to meow.
19:19He learns that humans respond well to vocalizations.
19:23We are a conversational species, so to speak.
19:26And so, a cat discovers that the best way to get its owner's attention is by making noise.
19:31Having done that, he indicates using some kind of body language what he wants: to eat, to go out, or to...
19:36Whatever.
19:39Cats have the same senses as humans, but they function in different ways.
19:44A cat's senses have evolved primarily to help it hunt.
19:50Even a tame cat like Mango has all those sharp hunter's instincts.
19:56For example, the eyes are at the front of the head.
19:59When Mango looks at something, each eye captures a slightly off-center image.
20:04The brain performs the centering, generating a three-dimensional image.
20:08Mango then knows the size of the object and how far away it is.
20:15Proportionally to the size of his head, Mango has much larger eyes than ours.
20:20They receive more light.
20:21And he can see just as well in semi-darkness as in broad daylight.
20:25Mango's eyes are so sensitive that they need pupils capable of restricting light in a way that...
20:31Our round pupils can't do it.
20:34Their pupils close almost completely into a slit.
20:38And when the light dims, they open up, occupying a proportionally much larger area of the eye than the pupils.
20:44Humans.
20:49Mango can't see in total darkness, but he sees with far less light than humans.
20:57Cats have a layer of cells called the tapetum lucidum at the back of their eye.
21:03Light that passes through the retina without being absorbed is reflected back, giving the receptors a second chance to...
21:10to capture it.
21:11This increases the efficiency of Mango's eyes by 40%.
21:15And to further increase efficiency, cats have more photosensitive cells that function better in lower light conditions.
21:25Despite all this, Mango can see in light six times dimmer than his human companion can.
21:37But cats aren't better than humans at everything.
21:40Even if he could be taught, Mango would never be able to read.
21:47His eyes aren't good at picking up small details, and he sees a printed page as a gray sheet of paper.
21:59A cat sees the world more or less like someone who has lost their glasses.
22:06And the cat doesn't see colors very well either.
22:09Cats sacrifice detail and color to see better at night.
22:15The colorful world of cats is faded.
22:18They see a little bit of yellow, green, and blue.
22:21But some colors, like red, they see as gray or black.
22:27Another important hunting tool is hearing.
22:30Mango can turn its ears, as well as its head.
22:33This helps to locate a sound.
22:37The tapered ears channel and amplify sounds like a megaphone.
22:45Cats hear sounds that people don't hear.
22:48The highest-pitched sounds, like the squeaks of a rat.
22:58And when a cat hears a squeak, it needs to know exactly where it came from.
23:05Depending on the relative intensity of the sound in each ear, the cat automatically turns its head in the right direction.
23:15Cats are also very good at detecting movement.
23:18But when they approach their prey, they need to use their sense of touch.
23:24This type of game gives the mango a chance to practice the routine of a hunt.
23:29He even uses his whiskers to feel the pity.
23:34Three times thicker than the other hairs on a cat, the whiskers, or vibrissae,
23:39They descend to a depth three times greater in the skin and have sensitive cells at their base.
23:45They give the brain minute-by-minute information about anything the vibratio touches.
23:53The front paws are also super sensitive and are used to explore new things and test food.
24:01The pads of their paws sense the speed of what passes over them.
24:08Information travels from the paws to the brain at the speed of an electric current.
24:16A cat can learn a lot about something simply by stroking or gently touching it.
24:24Cats' senses have been honed for hunting, but they are also useful in mating.
24:30When a female is ready to breed, she releases odors that are perceived by the Jacobson's organ in the male's nose.
24:37male.
24:43In a free group, several males will attempt to mate with the female.
24:46The kittens in the litter may have more than one father.
24:50By mating freely, the female ensures that at least some of her offspring will have the best genes available.
24:59This is also a strategy for maintaining peace.
25:02Since no male will be certain which of the offspring are his,
25:06He is less likely to hurt or kill any of them.
25:14Kittens are born completely vulnerable.
25:17Despite being covered in fur, they are unable to regulate their own temperature.
25:21They are also blind, deaf, and unable to walk.
25:25But all of this is good, because it means that under no circumstances,
25:29They will be separated from their mother and exposed to danger.
25:36Kittens follow the scent and warmth of their mother's teats.
25:40And they breastfeed for up to eight hours a day.
25:52When they are not breastfeeding, there is only one other thing they can do.
25:57Sleep.
26:02The transition from birth to maturity, by human standards, is very rapid.
26:06But to the kittens, it must seem slow.
26:09This one is ten days old.
26:10He can see a little, but his vision is still blurry.
26:14And it will continue like this for the next three weeks.
26:18At this age, it's not easy for a kitten to get around.
26:21He walks slowly and hunched over.
26:25To maintain stability.
26:35At three weeks old, the kitten is already standing and walking.
26:39Although still a little shaky.
26:44He doesn't yet walk on tiptoe, like an adult cat.
26:48It's a posture that takes some time to perfect.
26:52But as they gain confidence each day, the puppies demonstrate a growing need to explore and play.
27:02A week later, the game is more lively.
27:09In clearer water, vision is better, and the kittens begin to use their tails for balance.
27:18At five weeks old, the kitten begins to control most of the things that make it a cat.
27:24His walk is now more like that of a cat.
27:28Your directional hearing starts to work.
27:33And my vision improves every day.
27:44At six weeks old, walking is not enough.
27:48Playtime and cleaning are developing.
27:58At eight weeks old, just two months after being born, this is a young, yet fully developed, cat.
28:05From now on, he will only grow and improve.
28:14The development pattern is virtually the same for all types of felines.
28:18But domestic cats have another important lesson to learn.
28:27How to get along with people.
28:30Hello dear.
28:32These people in Bristol, England, are volunteers who pet lost and abandoned cats.
28:39Ah, good girl.
28:44Okay, okay, my dear.
28:48Oh, baby.
28:49Oh, look at all the beautiful kittens you have!
28:53Contrary to what people imagine, kittens are not born with the ability to interact with us.
28:58They have to learn.
28:59It's a learning process that begins when their eyes open and ends around seven or eight weeks later.
29:05age.
29:06A cat that receives a lot of attention and is handled frequently in the city tends to grow attached to people.
29:12He'll love jumping into your lap and being petted.
29:15A cat that is handled infrequently will be more aloof, the type that tolerates human presence but not the environment.
29:20search.
29:22If they don't encounter people during this critical period, it's unlikely they'll be friendly.
29:27The tendency is for them to be wild.
29:31Stray kittens that are never petted will never have this kind of life.
29:34Volunteer Dawn England.
29:36We try to place them in an environment that is as similar as possible to a home, with curtains, rugs, and chairs.
29:43That way, when they go to a house, they won't be disconcerted and will know what to expect.
29:48The intention is for the kittens to be easy to handle.
29:51Of course, people tell us how good and well-domesticated they are, and that's what we want.
30:04Technically, domestic cats and wild cats are the same species.
30:08The two main differences are the social skills of the domestic cat, both with people and with other cats.
30:16And its color.
30:26Domestic cats don't need camouflage.
30:29And free from this requirement, the striped fur of the ancestors, known as tebi,
30:34It gave rise to almost every pattern and color an animal can have.
30:52Black was the first new color.
30:58Around 2,500 years ago, the Phoenicians managed to smuggle cats from Egypt and use them as rat traps on their ships.
31:06And many of those cats were black.
31:18Trading throughout the Mediterranean, the Phoenicians established colonies in various locations.
31:24Like Carthage
31:28and Gades,
31:30which is now Cadiz, in Spain.
31:34And the black cats went with them.
31:40Over time, cats established themselves all around the Mediterranean.
31:44The ancestors of the black cats that roam Venice today,
31:48They probably came from Phoenician ships.
31:55About a thousand years after the Phoenicians, the Vikings became the great maritime power.
32:01Their ships also had cats, but they preferred the Red Tabs, with their reddish stripes.
32:10This is a color that appears to have originated in ancient Türkiye.
32:14With Viking navigators, the Red Tabs sailed up and down the rivers of Europe and reached as far as Scandinavia.
32:22Christmas.
32:33It was on ships that cats of all kinds spread throughout the world.
32:38All places on the planet inhabited by humans are also inhabited by cats.
32:51And where cats went to land, their lives became intertwined with ours.
32:57This is Miami, Florida, home to one of the most exclusive cat shows in the United States.
33:03These are not domestic cats bred by chance.
33:08They are purebred cats, with expensive chains, brought here to gain prestige and prizes for their owners.
33:19Cat shows have been around for just over 100 years.
33:23And many modern breeds originated from exhibitions.
33:30Many cat types are variations of types that developed naturally in certain regions.
33:36A cat from Chateauê, linked to the Crusaders and Carthusian monks of France.
33:47Angora, which dates back to ancient Türkiye.
33:50From then until now, it has changed little and given rise to the fluffy Persian cat.
34:03Another furry friend is the Maine Coon.
34:06A cat that developed naturally in the cold of New England.
34:12The Abyssinian cat is an ancient breed.
34:15Even today, these elegant animals retain the appearance of the first cats that became associated with humans.
34:22It was a natural mutation that gave rise to the Japanese Bobtail.
34:26But today, it is a purebred.
34:34The Ossicat, with its machete-like markings, resembles a wildcat, but it was bred to look that way.
34:41The American Curl, with its unusual ears, is descended from a mutation discovered in 1981.
34:48The Cornish Rex, with its curly fur, is also a recent breed.
34:52It dates back to a mutation in a litter of farm cats 50 years ago.
35:00The Siamese
35:03Elegant and intelligent, it is one of the most popular cat breeds in the world.
35:07This is also an ancient breed, whose origins date back to Siam, present-day Thailand.
35:17One of the most fun cats I had the pleasure of treating this weekend was this Brown Tab.
35:25What I liked most about this cat was the fantastic harmony of her head, her short snout, her rounded skull and...
35:35The expression is beautiful, beautiful.
35:38Even though she's a little on the wild side.
35:43Champion of the show, the best cat in the show.
35:48Cats are different from all other domestic animals because they are not bred for a particular purpose.
35:55Simply to satisfy various human tastes.
35:57And when tastes change, cats change.
36:01A cat show that took place just over 40 years ago, and one Persian cat was entered.
36:09A Persian cat registered today.
36:13The current trend is that Persian cats no longer need a nose.
36:16And in the process of flattening the snout, the breeders ended up with an animal with distorted tear ducts and eyes that...
36:23They cry nonstop.
36:28The modern Siamese, an attempt to recreate what Westerners consider an Eastern look.
36:34A thin and frail animal, with health and reproductive problems.
36:41Forty years ago, a Siamese cat was more robust than those of today, but still more elegant and...
36:47more exotic than ordinary cats.
36:52Other modern variations of the Siamese cat.
36:55The face is no longer round, it's triangular.
37:02And here is the triumph of the creators' art.
37:05The sphinx, a hairless cat.
37:09But these are the aristocrats in the cat world.
37:14Far from the feline aristocracy of Miami, there are cats like this.
37:20Stray cats.
37:27They are domestic cats that have reverted to their wild state, along with their offspring.
37:31They live in colonies on the fringes of our lives, and to survive, they depend on each other and on human handouts.
37:38Come here, come here, come here, baby.
37:40Come here, little kitty.
37:42Oh, come here baby.
37:43In the United States, there are estimated to be 60 million cats living like this.
37:47Some cities have programs to sterilize stray cats.
37:50Here in Orlando, Florida, is the headquarters of CARE, a group dedicated to providing care for cats.
37:57Connie Graham and Barbara Logan capture and take cats to be neutered.
38:03I'm really looking for a friendly beige and white male.
38:06How old do you think he is?
38:08About a year.
38:09Many people think it would be better to sacrifice, to kill, these stray cats.
38:14And that's what has been done for years.
38:17The big problem is that it doesn't work.
38:21There are more stray cats out there than ever before.
38:24Nobody knows how many.
38:25It's impossible to count.
38:27But estimates are in the millions, tens of millions.
38:31These cats were someone's pets.
38:35And the people moved away and left them behind, they didn't want them anymore.
38:39They got tired of them and threw them somewhere.
38:41And cats that haven't been neutered or spayed end up finding other fertile cats and start breeding.
38:48And what starts with one or two cats suddenly becomes a colony of 20 or 40.
38:53In an area where traps were set for our program, more than 80 cats were caught.
39:03In theory, a cat can produce thousands of offspring.
39:07Of course, natural causes prevent this from happening.
39:11But it would be better for everyone if stray cats never reproduced.
39:16Cats are not always easy animals to catch.
39:20But in Orlando, throughout Orange County, organizations like CARE pick up as many as they can.
39:26Always with backup nearby and always prepared to avoid stressing the animal.
39:34At the sterilization clinic, cats arrive from all over the city.
39:41Even puppies.
39:43It is hoped that they will soon find a loving home.
39:50It's almost like an assembly line.
39:53The cats are anesthetized, prepared, and taken away to be neutered.
39:58It is efficient and painless.
40:08Many are released on the same day, but others remain under observation until the following day.
40:13to make sure they are okay and that the anesthesia has worn off.
40:21Most return to the colony they came from and continue their lives.
40:25You're home, little one. Do you know where you are?
40:28Volunteers make regular visits and bring food.
40:32Ah, what a good boy. Good boy.
40:34If we help a little by sterilizing and vaccinating against some diseases they can catch,
40:43They will have a much better chance of living a normal and even long life.
40:49We don't believe they would be better off dead.
40:53Life is precious, and death is something we all have to face.
40:57But unnecessary death is something we want to avoid.
41:04There probably wouldn't be so many stray cats if people understood cats better and what it takes to care for them.
41:09to have them.
41:13Class, I have the pleasure of bringing you a special guest today. His name is Héctor.
41:16Just as kittens learn about people, children need to learn about cats.
41:21Who has a cat at home?
41:23Great. Roberto and Alexis have cats at home. What's your cat's name, Roberto?
41:28Kiko.
41:29Alexis, what's your cat's name?
41:31Fluffy.
41:32Fluffy.
41:33Well, Hector is going to bring three special cats.
41:37And we will pet them, we will learn their names and call them.
41:42And we're going to learn special things about them.
41:45Ready?
41:47Ready!
41:48Excellent.
41:50In Miami, Héctor Castaner and his cats, known as Buster and the F team, take the message to schools.
41:57Look what I brought today.
41:59AND!
42:01Oh, how cute!
42:02This is the Flashback.
42:04This is Buster.
42:06I want Buster.
42:07Yes, sir. Yes, sir. Buster. Come, Buster. Come.
42:10What's his name? Talk to him, talk to him.
42:13I want to hold Buster. I want to hold Buster.
42:18I want to play with him.
42:21This cat is helping people to help cats.
42:27And there are cats that help people help people.
42:30Merrin, I think I've found the specimens we were looking for of North African cheetahs.
42:36Great!
42:37Steven O'Brien, from the National Cancer Institute.
42:41We became interested in cats about 15 years ago, when we realized that there are a number of diseases that are
42:48fatal in humans and also in cats.
42:52It was in the late 1980s that the feline version of the AIDS virus was discovered.
42:58And we were curious to know if the virus that was causing the AIDS-like disease in cats
43:05had domestic animals affected some other species of feline?
43:12Perhaps we were at the beginning of an epidemic that would decimate all felines, just as human populations were being decimated.
43:22where AIDS epidemics emerged.
43:25It was a horrifying prospect. 36 species of felines in the world, almost all already at risk of extinction.
43:33And now, incredibly, they are threatened by AIDS.
43:39But the more blood samples the Institute collected from various feline species, the more it seemed there was something more to it.
43:46in this story.
43:47What we discovered was exactly what we didn't expect, namely, that virtually all feline species in
43:55The planet had some level of infection and exposure to the version of the virus that causes AIDS in domestic cats.
44:03But the difference is that these felines, the wild felines, at least the ones we examined, were not getting sick.
44:11They did not develop the immune deficiency, and that was a mystery.
44:16What happened to some of these felines was that they developed genetic defenses against a fatal disease, such as the virus.
44:24of AIDS.
44:25Understanding this in felines could lead us to discover a similar type of natural genetic mechanism in humans.
44:34As companions, cats and humans have a history that perhaps spans 4,000 years.
44:40But there's much more to this connection than just companionship.
44:43Both are mammals and both share a common genetic heritage.
44:47Could cats help reveal a genetic cure for human AIDS?
44:55In 1996, we were fortunate enough to discover the first gene that actually caused genetic resistance to infection by
45:03HIV.
45:04And this has led us to a goal, so to speak, of new drugs that mimic the effects of this genetic resistance.
45:13natural
45:13to a fatal infectious disease.
45:19By killing rats, cats are credited with containing the Black Death.
45:25Will studying your genes help stop a disease that, in certain parts of the world, has already affected...
45:30Epidemic proportions?
45:36After all, cats are our old friends.
45:40They arrived at the same time as civilization.
45:43And of all the animals we've domesticated, they're the only ones with whom we don't have a master-master relationship.
45:49subordinate.
45:52The cats chose to stay with us.
45:54And we live with them, inside our homes.
45:58For one simple reason.
45:59We like them.
46:01And they like us.
